Abstract (in english)
   In rock specimens selected from the KTB pilot borehole (gneiss and amphibolite) and from surface outcrops in the vicinity of the borehole (amphibolite) low-field and high-field magnetic anisotropies were investigated in order to resolve the total AMS into the ferrimagnetic and paramagnetic components. In weakly magnetic rocks, i.e. those with mean susceptibility less than 5 x 10-4, the paramagnetic anisotropy controls the rock anisotropy, while in strongly magnetic rocks the contribution of the ferrimagnetic component is stronger or even dominant. The orientations of the principal directions in both the components are coaxial
